The invention discloses a wear-resistant cable fixing hanger, comprising a first horizontal plate. The two sides of the bottom of the first horizontal plate are fixedly connected with fixing mechanisms. First sliding bars are fixedly connected to both sides of the top of the first horizontal plate. By means of the cooperation of the first horizontal plate, fixing mechanisms, a first fixing plate,a first screw, a second fixing plate, a third fixing plate, a second screw, the first sliding bars, a second horizontal plate, an adjusting mechanism, a bearing, a lead screw, a nut, a rotating disc,an engagement box, a fixing rod, a second sliding bar, a first fixing block, a driving rod, a second fixing block, a slide block, a third sliding bar, an engagement block, a first clamping block and asecond clamping block, the wear-resistant cable fixing hanger solves the problem that it is inconvenient for an existing fixing hanger to fix a cable, and the cable is easy to move after fixed, thereby causing inconvenience in cable fixation. The wear-resistant cable fixing hanger can achieve good convenience in fixation, and is improved in practicability.
